I guess my biggest qualm is that (some) people think there's really only one way to be feminine. I'm not what (most) people would consider outwardly feminine. That said, just by virtue of being female, makes me feminine. I don't think it makes a woman less a woman (and really, this is where the feminization argument comes to play) if she is strong, and can slay a dragon so to speak. One could argue that women who grew up in gang-plagued areas and who are violent aren't any less feminine, they're just more violent. I'll use female hispanic gang members for an example. They can be quite violent but often tend toward the very (society-conceived) feminine "look." Does their violence make them appear less feminine? Not so much, IMO.
I often think that when (some) people pull out the feminine card, what they often mean is they want their women to be weaker than men (I'm referring to mostly fiction here). That if a female protagonist is stronger than a male protagonist, this somehow emasculates the male and I think that's the wrong way to look at it. If a female protagonist is stronger than the male, it just means that she doesn't need to be rescued. There's nothing inherently wrong with being rescued but women do not need to be rescued as often in real life as they seem to be in fiction. Telling men or women through fiction that their gender roles are in danger because they did or didn't rescue someone adds to the problem women face in our society. If we continually read that women need to be rescued, then (some) men will continually seem to see us as weaker because of that need and if he encounter's a woman who doesn't need to be rescued that makes her threatening because he can't act on his preconceived role--which could be interpreted as damaging his ego.
I don't know, I'm mostly pulling opinion from where the sun don't shine but it's the way I see it, right or wrong. Mama didn't raise no psychology major but she did raise a thinker.
